ok doug, more will be clear when i get up all the photos, but ill help ya out a bit now.

1. the mines that were being flushed closed around the 40s. so there were pretty much no more entrances near by that were open, or safe so they drilled a 42" borehole and installed this pod. there was a second drilled with a fan on top for ventilation. some locations used a few old mine entrances for second openings. this way they could put the pod hole right where they needed it. this was called controlled flushing, where they went into the mines and put the flush where they wanted it. another way was just to drill 10-12 inch bore holes and fill the workings till the flush came out another hole. our buddy tony (miner490) wrote up a real good description of the project we will be adding soon.

That was the Hickory Street flushing project. It is one of the earliest mines, (if not the oldest) in Scranton. It was developed by the Lackawanna iron & coal company. With much of its output being used in the iron furnaces located very nearby. And also the Lackawanna and Wyoming Valley ( Laural line) railroad.. being part of there National mine. Later it was absorbed by the Pennsylvania coal company becoming there Underwood No. 5. The project itself took place many years after controlled flushing fell out of favor. But it was not a controlled project per say. Flushing was still " blind". But certain areas were opened to demonstrate to various officials and local media exactly how flushing underground was performed, and the results of the project itself. A movie was even supposed to be made , but never materialized. Another purpose of this project was to see how different sized flush material 1/2 in vs. 3/4 vs 1 in spread out . The distance each borehole could cover under those conditions. ( the black and whilte photo) The veins that were flushed were the Clark and New County ( uppermost beds in that area) The Clark took 525,000 tons, 1 The New County 176,000. Funds ran out on the project, and some areas remain open to this day. Work began on August 12,1977 and was completed during May of 1980.
